Application

Misting SA is using environmental control to increase profits, by maintaining product quality and reducing wastage

In order to ensure superior quality tobacco it is essential to retain the appropriate relative humidity during production. As tobacco is a plant with high moisture content, it loses moisture within a dry environment, you are guaranteed shrinkage, flaking, brittleness, splitting and loss of weight of tobacco. The correct level of humidity can prevent aforementioned problems, with the ideal moisture content being about 15%.

The use of Misting SA’s misting systems during tobacco production takes less water than other methods, it is advised to mist for several times for a shorter period. For efficient production it is essential to maintain the RH between 60-70%, this will guarantee that tobacco, paper and leaves retain moisture at the proper levels.

Recommended RH levels

The different phases during tobacco production require different humidity levels and temperature.

How does Misting SA control the environment?

With the use of Misting SA’s series of speciality MIST nozzles placed in a line around the perimeter of an area, or by using specially designed MISTING rings, attached to box / oscillating fans, when connected to a high pressure MISTING system pump, water is forced through the specialty nozzles and quickly atomized to droplets as small as (5 microns).

Misting systems will produce billions of tiny droplets every second. If these droplets are introduced into an outdoor area, they quickly evaporate. This process of evaporation requires energy to be completed. The energy is taken from the air in the form of heat. The result is a temperature reduction of up to 12 degrees, depending on the ambient temperature and the relative humidity of the air. This method of temperature reduction is the most common use for all MISTING systems.
When misting systems are placed inside an enclosed area (such as a greenhouse), the billions of droplets that are produced will initially provide cooling as the droplets evaporate. However, if the air exchange is limited, the misting system will continue to increase the humidity level within the structure. Humidity levels as high as 90+% are possible. This unique characteristic of all misting systems makes them ideal for both outdoor cooling and humidification.
